Abstract

An optical arithmetic processor for digital addition will be one of the most important basic elements in optical computers. Several optical implementations of half or full adder circuits have been proposed ^1-4 However, dynamic processing has not been developed for parallel digital addition. The main problem is real-time parallel operation of the half adder and the dynamic construction by cascadable configuration.
